FreeBSD : openvpn-devel -- arbitrary code execution (c61ca9cb-64c3-11dd-954d-006097bcc5f4)

Synopsis :

The remote FreeBSD host is missing a security-related update.

Description :

James Yonan reports :

Security Fix - affects non-Windows OpenVPN clients running OpenVPN
2.1-beta14 through 2.1-rc8 (OpenVPN 2.0.x clients are NOT vulnerable
nor are any versions of the OpenVPN server vulnerable).

An OpenVPN client connecting to a malicious or compromised server
could potentially receive an 'lladdr' or 'iproute' configuration
directive from the server which could cause arbitrary code execution
on the client. A successful attack requires that (a) the client has
agreed to allow the server to push configuration directives to it by
including 'pull' or the macro 'client' in its configuration file, (b)
the client succesfully authenticates the server, (c) the server is
malicious or has been compromised and is under the control of the
attacker, and (d) the client is running a non-Windows OS.
